How much does the 2021 Audi A4 cost?

Prices have softened 7.94% compared to this time last year, making it a favorable time to shop this model year.

There are 347 listings available, which gives you a modest amount of inventory to compare before you buy.

Is the 2021 Audi A4 a good car?

Yes — the 4.75/5 user rating points to strong owner satisfaction. The 2021 A4 is described as a well-rounded compact luxury sedan that blends efficiency, technology, and everyday usability, with a power bump and mild-hybrid setup that improve its performance edge. It also offers available quattro all-wheel drive for added traction, plus a modern cabin with Virtual Cockpit and an upgraded MMI system. The tradeoffs are that the base engines are underwhelming and the back seat is cramped, so it fits you best if you value tech and refinement more than rear-seat space. 33.1% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2021 Audi A4 reliable?

Owners rate it 4.75/5, a strong signal of long-term satisfaction.

The 2021 A4 is presented as a well-rounded, usable sedan with a strong technology package and a more confident powertrain than its base-engine reputation suggests. Its available all-wheel drive can also add confidence in poor weather, which matters if you plan to keep the car through changing seasons. For a used buyer, the main long-term ownership risk is making sure the specific car you choose has been maintained well and hasn’t been compromised by prior damage or neglect.

What should I look for when buying a used 2021 Audi A4?

At 73.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can separate clean examples from cars with prior damage. After that, prioritize a thorough pre-purchase inspection, with extra attention to bodywork, panel alignment, and signs of uneven wear that could point to past repairs. Because this model’s appeal depends heavily on its balance of technology and everyday usability, you should also focus on cabin condition and make sure the electronics and interior features work as expected.

Is now a good time to buy a used 2021 Audi A4?

This looks like a moderate, selective buyer’s market, so you can shop patiently but still move quickly on the right car.

• Deal availability: 33.1% of listings are priced as good or great deals.
• Inventory: There are 347 listings available.
• Price trend: Prices have softened 7.94% compared with last year.
• Clean inventory: 73.2% of listings are accident-free.

If you find a listing below $21,478, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Audi A4's resale value?

The current average of $21,707 sits slightly below last year's $23,579.

That decline suggests the market has become a bit more favorable for buyers, but it also means sellers may need to price competitively to stand out. If you own one and plan to sell later, the current trend shows that value has softened, so timing and condition will matter. Well-kept examples with desirable equipment should still draw attention, especially if they present cleanly and have a strong service history.

Vehicles with strong owner satisfaction ratings, like this model year's 4.75/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Audi A4 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 33.1% of listings are priced as good or great deals.
• At 73.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.94% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.

Consider the 2022 if:

• At $23,014, the 2022 costs more than the current year's $21,707 average.
• It feels remarkably fresh and brings modern technology with a rock-solid structure.

The bottom line: If you want the better value play, the 2021 is the stronger starting point because it combines a lower average price with solid owner satisfaction and meaningful inventory. If you’re willing to pay more for a newer-feeling alternative, the 2022 is the better secondary path for buyers who want the freshest version and can stretch their budget.
